Application filed February 21, 1922. Serial No. 588,322;

T 0 all 10 ham it may concern:

Be it known that l, EDWARD E. Roenns, a citizen of the United States, and'resident of the city of New York, boroughof Bronx, county of Bronx, and State of New York, have invented a new and lmprovedSharpening Device, of which the following is a full, clear, and exact description,

vice and aims to provide certain new and useful improvements in connection with a machine of this character.

It is an object of this invention to provide a device of the type stated which shall be extremely simple in construction and capable of being placed upon the market at a nominal figure, aside from the fact that the same shall .be capable of being utilized by an operation of the greatest simplicity.

A further object of this invention is that of constructing a sharpening device by means of which knives and similar cutting elements may quickly have an edge formed upon their blade, it being noted however that this edge is formed by a manual operation-and without the aid'of any mechanical or electrical operating members.

Still another object of this invention is that of providing a sharpening device of the type stated in which theposition and subsequent actuation of the blade to be sharpened will result in the operation of the parts of the device so that the operation of the latter is reduced to the simplest terms possible.

A still further object of this invention is that of providing a sharpening device embodying the aforementioned qualifications; and which in addition to being capable of placing a cutting edge upon a knife will also lend itself to the forming of a-proper cutting edge upon apair of shears.

Still further objects of this invention will become apparent in the annexed specification taken in connection with the drawings which latter illustrate one practical embodiment of the same, and in which;

igure 1 is a sectional'side view of a sharpening device.

Figure 2 is a plan view thereof, both of these figures showing my device while the parts are being actuated to sharpenn knife.

Figure 3 is a plan view similar to Figure 2 but showing a portion of the cover broken away to disclose the underlyin 5 construction and also showing a pair of sears applied to the said sharpening device, and

My invention relates to a sharpening de- Figure 4-is an end view thereof.

Specification of Letters Patent. Patented Au 22, 1922,

llt will be seen in these views that the reference numeral 5 indicates the base of the device to which spaced side walls o'are secured, the latter supporting adjacent their upper edges, platforms 7 having their adj acent edges spaced and preferably provided with guide flanges 8.

Positioned within the enclosure thus provided are shafts 9 which are angularly disbase, and have their axis arranged substanposed with respect to the side walls and the tially at right angles with respect to each other; it being noted that their lower ends are rotatably supported in line with each other, as has been shown in Figures 2 and 4. A pair of drums 10 are afixedone to each of the shafts and supported thereby, these drums being spaced from each other as in Figure 2, and having their contact faces disposed at that an letothe vertical corresponding to the ang e at which a cutting edge should be formed with respect to the body of the blade.

seen that a bladell may be brought to ex-' tend into the slot formed by the spacing of the platforms 7, and this blade is brought-to so i Thus as in Figures 1, 2 and l it will be through the body of the sharpening device and when this action is resorted to a rollingand grinding contact will be established between the cutting edge oil? the same and the faces of the abrasive drums so thatupon this "operation bein repeated a number of times the blade wil be properly sharpened.

Furthermore, as has been clearly indicated one of the sidewalls 6 is preferably formed with aslot 12,and one of the end ed es of the platform 7 secured to this side we 1 is extended downwardly as at 13 to pro= vide a guide. r'lhus it will be obvious that .a shear may have one of its blades brought I to extend through the slot 12, asin Figure 3, and it will be seen that theextendeol portion 13 in'this fiance, actsas a de tor the shear to steady the same when its cutting edge is in contact with the outermost of the abrasive drums 10. Also due to-the angular disposition of this drum with respect to the side wall and slot, and consequently with respect to the shear blade extending through the slot, it will be obvious that a proper con- Without in the least departing from the scope of my claims; which are 1. A grinding device including a base, a platform extending above and in spaced relationship to said base, said platform being formed with a slot,guide flanges formed adj acent to said slot, shafts extending between said platform and said base, said shafts being rotatably mounted and disposed at an le to each other and to the said slot and form secured to said side walls and in spaced relationship to said base, grinding members disposed between said platform and base, said platform being formed with a slot at a point above said grinding members, one of said side walls beingformed with a slot in line with one of said grindin members.

8. A grinding device including a base, side walls extending from said base, a platform secured to said side walls and in spaced relationship to said base, grinding members disposed between said platform and base, said platform being formed with a slot at a point above said grinding members, one of said side walls being formed with a slot in line with one of said grinding members, and an outer wall forming a part of said device and in line with one of the edges of said last named slot, said wall being adapted to act as a guide.
